I've just tried the new beta version 1.18 with the following result:
After starting MyPhotoIndex the Database was converted (apx. 10000 images!), no message was given (made a backup 
After the conversion (2 min) all data was there but the images where not found (not found image) ....
back to version 1.17, with the backup files, everything was working fine..
It looks like the conversion is not 100% yet
P.S. There is a small ungrammatical bug in the import wizard -> from disk
memually --> manually
Keep on this great project!
